Description
Technical field
The utility model is related to the stator core insulation structures of motor field more particularly to a kind of motor.
Background technology
At present, there are three types of traditional stator core insulation structures：One kind is spliced using upper and lower two pieces of insulating bushings.
This may be used for sectional type and the little stator core of iron core thickness, but for completely circular structure and folded thickness rate compared with
For big stator core, it is easily deformed after being lengthened because of bushing slot inside points, leads to assemble very inconvenient and different iron
Core thickness needs the bushing with different height, leads to that bushing type is various, and cost input is big.
Second is using upper and lower two pieces of insulating end plates, and centre is spliced using insulating paper.This mode can use
Different insulating paper height is only needed replacing in full circle and folded thick big stator core, different stator cores, is tied compared to upper kind
Structure is better.But two end plates are easily deformed up and down, cause to contact defective tightness, intermediate insulating paper with stator core face
It is that thermoforming is also easy to cause deformation and causes to have contacted not close and more the process for inserting insulating paper together, cost with stator core
It is higher.
The third is to realize to insulate with insulation framework integral molded plastic using stator core, and traditional injection structure mainly uses
In external rotor electric machine, major defect is that motor down-lead and insulating sleeve etc. can not be fixed after stator is molded, and is distributed inside motor
Confusion, so can only be moulded in wire connection terminal etc. in insulation framework together, this allows for having inside stator core sufficiently large
Space, in the motor of stator interior be inapplicable for rotor.
